Description

The elastic-buckle structure of a kind of pull head body and cap

Technical field

The utility model relates to a kind of zipper, and the syndeton especially relating to pull head body in pull head and cap is improved.

Background technology

At present, the pull head in zipper product, its cap is directly get riveted ready on the pull head body mostly.The cap of Chinese patent literature CN203328081U zipper head disclosed in the 2013.12.11 can be consulted; 2009.02.04 disclosed CN201188933Y slider head structure; 2011.06.26 disclosed CN201878913U zipper head.Above-mentioned patented product there will be distortion and affects outward appearance when directly getting ready on cap structure body, also can cause the distortion of pull head nose and affect its using function, even occurring that getting post-tensioning ready climbs problem not up to standard.

Utility model content

For problems of the prior art, the utility model provides the elastic-buckle structure of a kind of pull head body and cap.This elastic-buckle structure makes pull head body be connected with cap not only surely to lean on, and does not damage cap component, guarantees the using function of pull head and complete attractive in appearance.

For achieving the above object, the utility model adopts following technical scheme:

An elastic-buckle structure for pull head body and cap, described cap is connected on pull head body; There is lug at described cap two ends respectively to downward-extension, and lug is connected as a single entity by two pinches separated and forms; The bottom of two pinches is oppositely outwards bent to form hook portion, is provided with a recess between the lateral border of two pinches and hook portion; The upper flange upper surface of described pull head body is arranged with the vertical deep gouge matched with lug downwards, and described vertical deep gouge is made up of the upper counterbore communicated and lower deep gouge, is right angle in the joint of described upper counterbore and lower deep gouge; During installation, the they fit of cap, in the vertical deep gouge of pull head body, is fastened in lower deep gouge to make the hook portion elasticity of lug open, and recess and the right angle of vertical deep gouge of lug have that certain interval is corresponding to be arranged.

The elastic-buckle structure of a kind of pull head body as above and cap, the lateral border of described lug two pinch is inclined-plane, forms up-narrow and down-wide lateral border to make lug.

The elastic-buckle structure of a kind of pull head body as above and cap, the leading flank of described pull head body is provided with the horizontal through hole communicated with the lower deep gouge of vertical deep gouge.

The usefulness of technique scheme is:

The syndeton of the utility model pull head body and cap is the elastic deformation by being arranged on the lug on cap, locates to be inserted in the vertical deep gouge on pull head body.What the utility model abandoned prior art gets structure ready, the elastic-buckle structure be made up of lug and vertical deep gouge solves the cap deformation effect outward appearance occurred when directly getting ready on cap structure body, and directly get ready and make pull head body at bridge of the nose place its using function of deformation effect, solve cap structure body simultaneously and get rear existence ready and draw and climb problem not up to standard.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

A kind of pull head body as Figure 1-5 and the elastic-buckle structure of cap, described cap 10 is applied this elastic-buckle structure and is connected on pull head body 20.This elastic-buckle structure comprises the lug 30 be arranged on cap 10, and is arranged on the vertical deep gouge 40 on pull head body 10.

Shown in Fig. 1,5, described lug 30 is arranged on cap 10, is included in the forward and backward lug of cap two ends respectively to downward-extension.Forward and backward lug is connected as a single entity by the left and right pinch 31,32 separated and forms.The bottom of left and right pinch 31,32 is oppositely outwards bent to form hook portion 311,321, is provided with a recess 312,322 between the lateral border 313,323 of left and right pinch 31,32 and hook portion 311,321.

Incorporated by reference to the pull head body 20 shown in Fig. 1,3,4, its upper flange 21 upper surface is arranged with the vertical deep gouge 40 matched with lug 30 downwards, and described vertical deep gouge 40 comprises two the vertical deep gouges being arranged on the forward and backward position of pull head body 20.Described vertical deep gouge 40 is made up of the upper counterbore 41 communicated and lower deep gouge 42, is right angle 43 in the joint of described upper counterbore 41 and lower deep gouge 42.

During installation, the lug 30 of cap 10 is engaged in the vertical deep gouge 40 of pull head body 20, be fastened in lower deep gouge 42 to make hook portion 311,321 elasticity of lug 30 open, and the recess 322 of lug 30 and the right angle 43 of vertical deep gouge 40 have, and certain interval is corresponding to be arranged.

The lateral border 313,323 of the left and right pinch 31,32 of lug 30 is not only inclined-plane by the utility model, forms up-narrow and down-wide lateral border to make lug 30; The horizontal through hole 44 that the lower deep gouge 42 being also provided with deep gouge 40 vertical with this at the leading flank of pull head body 20 communicates, injects vertical deep gouge 40 more smoothly to make lug 30.

Above-mentioned explanation illustrate and describes preferred embodiment of the present utility model, as previously mentioned, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in utility model contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
